He is currently fighting for the right to see Hons. The older three children were taken into state custody in 2009 as part of proceedings which were sparked after a shop refused to decorate a birthday cake with the name of their oldest child, Adolf.

Campbell told The Sun: “There was no evidence of abuse so what’s wrong with the name Adolf Hitler? It’s cute. My son is named after a great war hero.”

The 40-year-old Holocaust denier (he says there is “no evidence” it occurred) added: “I don’t do hate crimes. And I wouldn’t advocate the extermination of other races, just for them to live separately.

Campbell leaves the family court, where proceedings are closed

“I am not hurting anyone. I am a good neighbour. The old lady who lives next door to me is disabled. I help her with her wheelchair.

Last Monday ahead of the hearing, Campbell told NBC News: “I’m going to tell the judge, I love my children. I wanna be a father, let me be it.”

NewJersey.com reports that although family court proceedings are closed, a 2010 appeal decision said the children's removal was not because of their names, but based on allegations of domestic violence.

Campbell says his three oldest children have since been adopted by other families. His youngest child, Hons, was taken into care hours after his birth in November 2011.

Campbell and his estranged wife Deborah have always denied abusing their children.

Outside the courthouse, Campbell added: "I've never abused my children, I only name my children and I don't think it's right anymore.
